Genesis 48:16
“הַמַּלְאָךְ הַגֹּאֵל אֹתִי מִכָּל רָע יְבָרֵךְ אֶת הַנְּעָרִים וְיִקָּרֵא בָהֶם שְׁמִי וְשֵׁם אֲבֹתַי אַבְרָהָם וְיִצְחָק וְיִדְגּוּ לָרֹב בְּקֶרֶב הָאָרֶץ”
“The angel who has redeemed me from all evil, Bless the lads; And may my name live on in them, And the names of my fathers Abraham and Isaac; And may they grow into a multitude in the midst of the earth.””

‘has redeemed me from all evil’ means that he never came close to the negative side and couldn’t control or harm him.
‘Bless the lads’ – Jacob connect the angel that protected him to the ‘lads’. These lads are the aspect of the higher angels, Metatronמטטרון and סנדלפון Sandalfon (Please do not pronounce these sacred names. Use ‘angel Metat’ and ‘angel Sandal’ to refer to them).
‘And the names of my fathers Abraham and Isaac’ refers to Jacob’s connection to the Right and Left column to open the central column for blessings to come down.
As we mentioned in previous study, we use this verse when we bless our children. We raise both hands to the right and left of the child’s head, meditating on Chessed (Right), Gevurah (Left) and we are in the middle as Central column, drawing the light from above to the child.
‘And may they grow into a multitude in the midst of the earth’ – this final step draws the blessings from above to the ‘sea’ of Malchut.
